12 CHAPTER 1: INTRODUCING THE SUPER STACK 3 SWITCH 3812, S WITCH 3824, AND SWITCH 3848About the Switch The Switch 3812, Switch 3824 and Switch 3848 units are10/100/1000 Mbps Ethernet Switches which consist of either:■ 12 10BASE-T/100BASE-TX/1000BASE-T RJ-45 ports (Switch 3812) or■ 24 10BASE-T/100BASE-TX/1000BASE-T RJ-45 ports (Switch 3824) or■ 48 10BASE-T/100BASE-TX/1000BASE-T RJ-45 ports (Switch 3848)and:■ Four SFP portsThe highest four numbered RJ-45 ports are combination ports. When anSFP module is inserted it has priority over the 10/100/1000 port of thesame number (9–12 on the Switch 3812, 21–24 on the Switch 3824, and45-48 on the Switch 3848).For information about using the software features of the Switch, refer tothe “Switch Management Interface Reference Guide” on the CD-ROMthat accompanies the Switch.Summary ofHardware FeaturesTable 3 summarizes the hardware features that are supported by theSwitch 3812, Switch 3824, and Switch 3848.Table 3 Hardware featuresFeature Switch 3812, Switch 3824, and Switch 3848MAC Addresses Up to 16,000 supportedForwarding Modes Store and ForwardAuto-negotiation Supported on all portsAuto MDI/MDIX Supported on all 10/100/1000 portsDuplex Modes Half and full duplex on all 10/100/1000 ports whenrunning at 10 Mbps or 100 Mbps.SFP Gigabit EthernetPortsSupports fiber Gigabit Ethernet short-wave (SX),long-wave (LX) and long-haul (LH70) transceivers in anycombinationFlow Control Supported on all portsTraffic Prioritization Supported (IEEE Std 802.1D, 1998 Edition)Eight traffic queues per portFast Ethernet andGigabit Ethernet PortsAuto-negotiating 10BASE-T/100BASE-TX/1000BASE-Tand SFP portsdua1740-0aaa03.book Page 12 Thursday, December 23, 2004 9:23 PM
